Since you seem to be connecting to the same port ( regardless
of where you attempt to connect FROM, I can only assume the machine
has only a single nic, Is that right?

Therefore, a connection to that nic from a local machine is
going to the same port as a connection from another lan.

It seems to me that the firewall is not really off, or that
there is a subnetting mask error such that packets can't get
back from
